Addex Therapeutics Ltd (SIX: ADXN, Nasdaq: ADXN), a clinical-stage pharmaceutical company pioneering allosteric modulation-based drug discovery and development, announced today that it has terminated the Phase 2b/3 study evaluating dipraglurant as a potential treatment for dyskinesia associated with Parkinson’s disease (PD-LID) due to the slow recruitment of patients. This has been attributed to the consequences of COVID-19 related patient concerns about participation in clinical studies as well as staffing shortages and turnover within study sites.
“We took this decision because it was not feasible to continue the study at such a slow recruitment rate in the current environment. I’d like to emphasize that it was not dipraglurant related and we continue to believe in the potential of this compound as a treatment for PD-LID,” said Tim Dyer, Chief Executive Officer of Addex. “We now plan to focus on advancing our preclinical portfolio towards the clinic and pursuing strategic collaborations for selected programs, while we concurrently focus on delivering under our strategic partnership with Indivior. Our strategic partner, Janssen is also expected to deliver data from the Phase 2 study of ADX71149 in epilepsy patients in the fourth quarter of this year.”
In light of the Company’s termination of the dipraglurant program for PD-LID, the Company is suspending the Company’s financial guidance.
